A Novel d10-d3-d10 Trinuclear Bimetallic Linear Complex of Zinc and Vanadium F. ALBERT COTTON,*'8 STAN A. DURAJ," WIESLAW J. ROTH," and C. DAVID SCHMULBACH*Ib Received May 31, 1984 The reaction of [V2(r-Cl),(THF)6]2[Zn2Cl6] with triphenylphosphine in benzene furnishes [V2(p-Cl)3(THF)~(PPh3)]2[zn2c16], which in turn gives (PPh3)(Cl)Zn(r-Cl)z(THF)V(THF)(r-Cl)zZn(C1)(PPh3) upon treatment with dichloromethane. The mono(tripheny1phosphine) derivative was characterized by elemental analysis and X-ray fluorescence measurements. The V[Zn(Cl)3(THF)(PPh3)]2-2CH2C12 molecule was fully characterized by single-crystal X-ray studies. The data are as follows: triclinic space group, Pi,a = 11.922 (3) A, b = 14.189 (2) A, c = 8.991 (3) A, LY = 107.47 (1)O, fl = 108.03 (2)O, y = 86.16 (1)O, V = 1379 (1) A,, Z = 1. The principal structural features of interest are as follows: Zn-V distance of 3.289 (1) A; Zn-P distance of 2.392 (1) A; Zn-Cl distances of 2.324 (1) and 2.293 (1) A for Zn-Cl(2)b and Zn
